Celebrity square meals: Martin Clunes' Cold Dog biscuits

Makes plenty

I have a lot of fun baking with my daughter Emily, and these Cold Dog biscuits are a real favourite with children, but lovely too with a mid-morning cup of coffee for grown-ups.

225g plain chocolate
225g butter
2 eggs
2tbsp caster sugar
225g digestive biscuits
60g mixed walnuts and cherries
1tbsp brandy

In a bowl set over a pan of boiling water (or even in a microwave), melt the chocolate and the butter. Place the digestive biscuits in a plastic bag and gently hit them with a rolling pin - you want them roughly broken, not crushed. Beat eggs and sugar together and then add them to the chocolate and butter, along with the biscuits. Stir in the walnuts and cherries, and the brandy (though the booze is optional).

Line a shallow cake tin with foil, butter it, and pour the mixture into it. Refrigerate for at least two hours.

When you're ready to eat it, cut it into squares and enjoy with a cup of coffee.
